The Old Town canoe with serial number 126154 is a 17 foot long, CS (Common Sense or middle) grade, Otca model with red western cedar planking, open spruce gunwales, birch decks, birch thwarts, birch seats, a keel, and a floor rack. It was built between December, 1938 and April, 1939. The original exterior paint color was dark green. It shipped on March 27th, 1940 to Palmyra, Pennsylvania. A scan showing this build record can be found below.
This scan and several hundred thousand others were created with substantial grants from the Wooden Canoe Heritage Association (WCHA) and others as you probably know well. A description of the project to preserve these records is available at
http://www.wcha.org/catalogs/old-town/records/ if you want more details. I hope that you will donate, join or renew your membership to the WCHA so that services like this can continue. See

It is also possible that you could have another number or manufacturer if this description doesn't match the canoe. Page five of the 1940 catalog at
